Radio Wave Repeater with Differing Antenna Directivity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing millimeter wave communication systems require drilling a hole through the outer wall of a building to connect indoor and outdoor antennas, limiting flexibility and increasing installation complexity.
Innovation Solution
A radio wave repeater system with a first antenna on one surface of a support and a second antenna on an opposite surface, connected by a transmission line, allowing for signal transmission and reception between inside and outside the building without needing a hole in the outer wall, with different directivity configurations for the antennas to optimize signal coverage and sensitivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hole is drilled through the outer wall to connect indoor and outdoor antennas, then signal transmission between inside and outside the building is achieved, but installation complexity increases and flexibility is limited
Solution Approach 1:
The patent introduces a repeater unit as an intermediary device that receives signals from the outdoor antenna and transmits them to the indoor antenna, eliminating the need for direct physical connection through wall drilling. The repeater unit acts as a mediator that bridges the indoor and outdoor communication environments.
Solution Approach 2:
The communication system is divided into separate functional components: an outdoor antenna, a repeater unit, and an indoor antenna. This segmentation allows each component to be installed and configured independently, removing the constraint of requiring a single continuous path through the wall.
2Reliability
If a hole is drilled through the outer wall for cable passage, then connection between indoor and outdoor antennas is established, but adaptability to varying radio wave environments is reduced
Solution Approach 1:
The system allows dynamic configuration where the repeater unit can be positioned at different locations and the antennas can be oriented in various directions to adapt to different radio wave propagation conditions, rather than being constrained by a fixed wall penetration point.
Solution Approach 2:
The repeater unit serves multiple functions: receiving signals from the outdoor antenna, amplifying/regenerating them, and transmitting to the indoor antenna. This multi-functionality provides flexibility in system configuration and adaptation to various installation environments.
3Ease of manufacture
If the same directivity is used for both outdoor and indoor antennas, then manufacturing and configuration is simplified, but signal coverage and sensitivity are compromised
Solution Approach 1:
The patent applies different directivity characteristics to the outdoor and indoor antennas based on their specific functional requirements and installation environments. The outdoor antenna may have broader directivity to capture signals from multiple directions, while the indoor antenna can be optimized for specific reception directions, enhancing overall system performance.

Implementation Method 1
a transmission line through which a radio frequency signal received at the first antenna is transmitted to the second antenna
Implementation Method 2
a transmission line through which a radio frequency signal received at the first antenna is transmitted to the second antenna and a radio frequency signal received at the second antenna is transmitted to the first antenna
Data Source
AI summary
A support has a first surface and a second surface, and directions of normal vectors of the first surface and the second surface pointing outside are different from each other. A first antenna is provided on the first surface, and a second antenna is provided on a second surface. A radio frequency signal received at the first antenna is transmitted through a transmission line to the second antenna, and a radio frequency signal received at the second antenna is transmitted through the transmission line to the first antenna. The first antenna, the second antenna, and the transmission line are configured such that the directivity of the first antenna is different from the directivity of the second antenna.
